1)
Take an A4 size paper.
2)
Take one corner of the paper and press it to its opposite diagonal end to give a diagonal crease.
3)
Cut the extra paper from the dotted line.
4)
You will get a square paper with one-sided diagonal.
5)
Turn the paper from the opposite side and press to get another diagonal.
6)
Now open the paper and you will get two diagonals passing on in it.
7)
Fold the paper half adjoining the two parallel ends and press.
8)
Open it and you can see a line passing through the X.
9)
Fold the paper again.
10)
Lift up the first layer, bring its top to the lower layer, tug it inside, and press.
11)
Then press the lifted upper layer on it. It will look like a rooftop.
12)
Similarly, curve the other end and tug it inside and press.
13)
It will become a triangle with sides tugged in.
14)
You will find two top flaps and two bottom flaps.
15)
Take the point of the top flap and place it on the top end of the triangle and press.
16)
Similarly take the other point, place it on the tip of the triangle, and press it.
17)
Then flip the object. Take the bottom of the triangle and fold it towards the top leaving some space above from the tip, then press it.
18)
Flip the object again. You will get the two tips of the flap. Take one flap and pull it downward, you will find it difficult as the side edge will be disturbing.
19)
Press the sides to some extent so that it does not disturb the tip of the flap to stretch down easily.
20)
Do the same with the other flap.
21)
Flip the object again to make the head.
22)
Bend the triangle that is on the top to its edge and press.
23)
Then again, fold the half of the small triangle towards the top so that the point should face upwards.
24)
Take both the wings of the butterfly and fold it on each other and press, then draw an imaginary line shaped V to the head.
25)
Fold the wings upwards on the lines of V shape and press hard. And you will find a beautiful origami butterfly ready.
